Design and bearing capacity analysis of cold-formed thin-walled steel-timber composite members

Cold-formed thin-walled steel has light weight, large width thickness ratio, good economy and seismic performance. It is easy to realize standardization of design, very suitable for the development prefabricated buildings. Due ratio cold-formed , plate prone local buckling when it compressed, which will reduce ductility bearing capacity structure, also leads limitation use structure system in medium high-rise In this paper, a kind steel-timber composite members designed. The section board are closely linked by bolts work together. spacing designed respectively, so as provide reference engineering design.
